The Food Additive Polyglycerol Polyricinoleate (E‐476): Structure, Applications, and Production Methods

International Scholarly Research Notices, Volume 2013, Issue 1, 2013., 2013
The food additive named polyglycerol polyricinoleate (PGPR) and identified with the code E‐476 (PGPR) is used as emulsifier in tin‐greasing emulsions for the baking trade and for the production of low‐fat spreads. However, the main application of PGPR is in the chocolate industry, where, besides its action as an emulsifier, it also has important ...

Production of Chemoenzymatic Catalyzed Monoepoxide Biolubricant: Optimization and Physicochemical Characteristics

BioMed Research International, Volume 2012, Issue 1, 2012., 2012
Linoleic acid (LA) is converted to per‐carboxylic acid catalyzed by an immobilized lipase from Candida antarctica (Novozym 435). This per‐carboxylic acid is only intermediate and epoxidized itself in good yields and almost without consecutive reactions.

Linking the yield stress functionality of polyglycerol polyricinoleate in a highly filled suspension to its molecular properties [PDF]

, 2022
Polyglycerol polyricinoleate (PGPR) is a food emulsifier with a unique yield stress reducing efficacy in fat-based suspensions. There are many commercially available PGPRs, and the different products vary in their impact on the yield stress. Choosing the

A comparative physicochemical property assessment and techno-economic analysis of biolubricants produced using chemical modification and additive-based routes

, 2022
Several edible and non-edible oil sources are currently being developed as renewable basestocks for biolubricant production. However, these feedstocks possess undesirable physicochemical properties limiting their lubricant applications.

Revisiting Securidaca longipedunculata Seed Oil: Applying NMR and Mass Spectroscopy to Confirm the Presence of 2‐Acetyl‐1,3‐Diacyl–sn‐Glycerols and Conjugated Hydroxydienoic Fatty Acids

Journal of the American Oil Chemists' Society, Volume 103, Issue 11, Page 1373-1383, November 2026.
The manuscript confirms and expands on previous reports concerning the presence of unusual conjugated hydroxydienoic fatty acids and acetyl‐TAG in the seed oil of Securidaca longipedunculata. The location of acetate only at sn‐2 of TAG was conclusively shown by high resolution NMR and hydroxy seed fatty acids are characterized.

Acute exercise‐induced lipolysis and increase in levels of fatty acid esters of hydroxy fatty acids in adipose tissue are impaired in obese and aged mice

Experimental Physiology, Volume 111, Issue 10, Page 4457-4497, 1 October 2026.
Abstract Improving adipose tissue (AT) metabolism through exercise might increase production of lipokines from the fatty acid esters of hydroxy fatty acids (FAHFA) family. Although exercise training can increase insulin sensitivity and levels of specific FAHFA in AT and the circulation in humans, the effects of acute exercise on FAHFA levels remain ...
